Which AWS service provides a simple and scalable shared file storage solution for use with Linux-based
AWS and on-premises servers?
A. Amazon S3
B. Amazon Glacier
C. Amazon EBS
D. Amazon EFS
```
Answer: D
Explanation:
Explanation:
Amazon Elastic File System (Amazon EFS) provides a simple, scalable, fully managed elastic NFS file
system for use with AWS Cloud services and on-premises resources. It is built to scale on demand to
petabytes without disrupting applications, growing and shrinking automatically as you add and remove files,
eliminating the need to provision and manage capacity to accommodate growth.
Amazon EFS is designed to provide the throughput, IOPS, and low latency needed for Linux workloads.
Throughput and IOPS scale as a file system grows and can burst to higher throughput levels for short
periods of time to support the unpredictable performance needs of file workloads. For the most demanding
workloads, Amazon EFS can support performance over 10GB/sec and up to 500,000 IOPS.

Which AWS service allows companies to connect an Amazon VPC to anon-premises data center?
A. AWS VPN
B. Amazon Redshift
C. API Gateway
D. Amazon Direct Connect
```
Answer: D
Explanation:
AWS Direct Connect enables you to securely connect your AWS environment to your on-premises data
center or office location over a standard 1 gigabit or 10 gigabit Ethernet fiber-optic connection. AWS Direct
Connect offers dedicated high speed, low latency connection, which bypasses internet service providers in
your network path. An AWS Direct Connect location provides access to Amazon Web Services in the
region it is associated with, as well as access to other US regions. AWS Direct Connect allows you to
logically partition the fiber-optic connections into multiple logical connections called Virtual Local Area
Networks (VLAN). You can take advantageof these logical connections to improve security, differentiate
traffic, and achieve compliance requirements.

How would an AWS customer easily apply common access controls to a large set of users?
A. Apply an IAM policy to an IAM group.
B. Apply an IAM policyto an IAM role.
C. Apply the same IAM policy to all IAM users with access to the same workload.
D. Apply an IAM policy to an Amazon Cognito user pool.
Answer: A
Explanation:
Instead of defining permissions for individual IAM users, it's usually more convenient to create groups that
relate to job functions (administrators, developers, accounting, etc.). Next, define the relevant permissions
for each group. Finally, assign IAM users to those groups. All the users in an IAM group inherit the
permissions assigned to thegroup. That way, you can make changes for everyone in a group in just one
place. As people move around in your company, you can simply change what IAM group their IAM user belongs to.

What technology enables compute capacity toadjust as loads change?
A. Load balancing
B. Automatic failover
C. Round robin
D. Auto Scaling
```
Answer: D
Explanation:
AWS Auto Scaling monitors your applications and automatically adjusts capacity to maintain steady,
predictable performance at the lowestpossible cost. Using AWS Auto Scaling, it’s easy to setup application
scaling for multiple resources across multiple services in minutes. The service provides a simple, powerful
user interface that lets you build scaling plans for resources including Amazon EC2 instances and Spot
Fleets, Amazon ECS tasks, Amazon DynamoDB tables and indexes, and Amazon Aurora Replicas. AWS
Auto Scaling makes scaling simple with recommendations that allow you to optimize performance, costs, or
balance between them. If you’realready using Amazon EC2 Auto Scaling to dynamically scale your Amazon EC2 instances, you can now combine it with AWS Auto Scaling to scale additional resources for
other AWS services. With AWS Auto Scaling, your applications always have the right resources at the right
time.
